NEW NanoVan™and Nano-W™ Pre-Made Negative Stains

Originally intended for staining samples with gold nanoparticles, these convenient ready-to-use pre-made negative stains have been since utilized for many other applications, including pre-screening samples for cryo-EM. NanoVan™is based on vanadium and thus gives lighter staining, for best visibility of gold and silver nanoparticles in the sample. Nano-W® is tungsten-based and recommended for those cases when higher contrast is desired; it is comparable to PTA negative stain.

Special organic compounds ensure better spreading and uniformity of the stain
